Zero trust rollout phases: what IAM teams need to prioritise

TL;DR: Zero Trust programmes often stall after MFA and admin lockdown because only 16% of organisations cover most of their systems, users, and infrastructure, according to Gartner. A phased rollout creates a practical path from foundational controls to contextual access and operational scaling, but it only works when teams treat Zero Trust as an operating model, not a one-time project.

NHIMG editorial — based on content published by JumpCloud: phased Zero Trust rollout guidance for scaling access control

By the numbers:

• According to Gartner, only 16% of organizations have Zero Trust protections covering most 75% or more of their systems, users, and infrastructure.
• 69% of security leaders agree identity management must fundamentally shift to address agentic AI systems.

Questions worth separating out

Q: How should security teams phase a Zero Trust rollout without losing momentum?

A: Start with controls that reduce immediate risk and are easy to standardise, such as MFA, admin account removal, and least privilege.

Q: Why do Zero Trust programmes often stall after the first few wins?

A: They stall when teams confuse partial control adoption with operational maturity.

Q: What breaks when Zero Trust only covers login and privileged access?

A: Security gaps remain in applications, cloud services, and machine identities that are not subject to the same verification discipline.

Practitioner guidance

• Sequence control rollout by risk boundary Start with MFA, least privilege, and admin account removal, then expand to conditional access and lifecycle automation only after the baseline is stable across core systems.
• Extend policy coverage beyond login Map which applications, cloud services, and machine identities still rely on static access rules, then bring them under consistent conditional access and review workflows.
• Automate provisioning and deprovisioning Tie joiner, mover, and leaver workflows to identity sources so access removal happens at the same speed as access creation, including for service accounts and shared credentials.
